This article is a celebration of the centenary of Schwarzschild's presentations of his external and internal solutions describing spacetime outside and inside an incompressible, spherically symmetric ...body. I give a review of these solutions and how they have been interpreted physically.
In this article it is argued that a continuity exists between Karl Schwarzschild's work on foundational problems on the borderline of physics and astronomy and his later occupation with general ...relativity. Based on an analysis of Schwarzschild's published works as well as formerly neglected unpublished notes it is shown that, long before the rise of general relativity, Schwarzschild was concerned with problems that later became associated with that theory. In particular he considered non-Euclidean cosmologies, linked the phenomena of gravitation and inertia to the problem of the precession of Mercury's perihelion, and entertained the possibility of inertial frames rotating with respect to one another. It is argued that these earlier considerations, which reflect his interdisciplinary outlook on the foundations of the exact sciences, enabled Schwarzschild to recognize the significance of general relativity for astronomy, astrophysics, and cosmology earlier than most of his collegues and shaped his contributions to this theory.

Shortly after Einstein proposed his general theory of relativity, a German physicist called Karl Schwarzschild found one of the first and most important solutions to Einstein's field equations. Now ...known as the Schwarzschild solution, it describes the geometry of space-time around extremely dense stars--and it has some very strange features. For a start, right at the center of such bodies, the curvature of space-time becomes infinite--forming a feature called a singularity An even stranger feature Is an invisible spherical surface, known as the event horizon, surrounding the singularity Nothing, not even light, can escape the event horizon. One can almost think of the Schwarzschild singularity as a hole in the fabric of space-time.
